Hyperthyroiwhatnowhizzle?

I just heard one of my No Tails say I need to go back to the vet to get checked for "hyperthyroidism," otherwise known as BEING A KITTEN.  

I'm not even a year old here, people!  I run around sometimes, okay?  And so what if I eat three times what the other cats do?  Running burns calories.

Damnit.
